All claims for indemnification under the Agreement shall be asserted and resolved as follows, provided that the provisions of Sections 6.3 through 6.6 shall be covenants and not conditions to the defense and indemnity obligations to which they apply: (a) Third Person Claims. In the event that any claim for which a Party providing indemnification (the "Indemnifying Party") would be liable to a Party or any of its officers, directors, employees, agents or representatives entitled to indemnification hereunder (the "Indemnified Party") is asserted against or sought to be collected by a third Person, the Indemnified Party shall promptly notify the Indemnifying Party of such claim, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim)(the "Claim Notice"). The Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Party (i) whether or not it disputes its liability to the Indemnified Party hereunder with respect to such claim; and (ii)whether or not it desires, at its sole cost and expense, to defend the Indemnified Party against such claim; provided, however, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading, submission or document which it shall deem necessary or appropriate to protect its interests. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend against such claim or demand, then, except as hereinafter provided, the Indemnifying Party shall have the right to defend such claim or demand by appropriate proceedings, which proceedings shall be promptly settled or prosecuted to a final conclusion, in such a manner as to avoid any risk of the Indemnified Party becoming subject to liability. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its own cost and expense. If the Indemnifying Party does not elect to defend against such claim, whether by not giving timely notice as provided above or otherwise, the Indemnified Party shall have the right but not the obligation to defend against such claim, and the amount of any such claim, or if the same be contested by the Indemnifying Party or by the Indemnified Party, then that portion thereof as to which such defense is unsuccessful, shall be conclusively deemed to be a liability of the Indemnifying Party hereunder (subject, if it has timely disputed liability, to a determination that the disputed liability is covered by this Part Six). (b) Other Claims. In the event that the Indemnified Party shall have a claim against the Indemnifying Party hereunder which does not involve a claim or demand being asserted or sought to be collected from it by a third Person, the Indemnified Party shall promptly send a Claim Notice with respect to such claim to the Indemnifying Party.

If there should be dispute as to the amount or manner of determination of any indemnity obligation owed under this Part Six, the Indemnifying Party shall nevertheless pay when due such portion, if any, of the obligation as shall not be subject to dispute. The difference, if any, between the amount of the obligation ultimately determined as properly payable under this Part Six and the portion, if any theretofore paid, shall bear interest at the Agreed Rate. Upon the payment in full of any claim, the Indemnifying Party shall be subrogated to the rights of the Indemnified Party against any Person or other entity with respect to the subject matter of this claim. (b) Payment of Interest. If all or part of any indemnification obligation under the Agreement is not paid when due upon resolution of the claim, then the Indemnifying Party shall pay upon demand to the Indemnified Party interest at the Agreed Rate on the unpaid amount of the obligation for each day from the date the amount became due until payment in full. 6.5 Limitation of Claims. Any claim for indemnity under this Part Six shall be subject to the following limitations: (a) Time Limitation.

(b) Amount Threshold. Claims for indemnity by the Indemnified Party shall be subject to the limitation that the Indemnified Party shall not be entitled to indemnification from the Indemnifying Party (i) with respect to any individual claim, unless the Losses for such claim incurred by the Indemnified Party exceeds One Hundred Thousand dollars ($100,000) (the "Claim Threshold"), and (ii) unless and until the aggregate Losses for all claims incurred by the Indemnified Party exceeds Five Hundred Thousand dollars ($500,000) (the "Aggregate Threshold"), whereupon the Indemnified Party shall be entitled to indemnification hereunder from the Indemnifying Party for all Losses from those claims individually exceeding the Claim Threshold.

In no event shall Buyer's aggregate liability under Part 6 exceed Three Million Dollars ($3,000,000).. 6.6 Disputed Claims. If the Indemnifying Party shall notify the Indemnified Party during the Notice Period that it disputes any claim under Section 6.3 (the "Disputed Claim"), the Disputed Claim shall be subject to the dispute resolution procedures provided in Section 8.12. 6.7 Exclusivity; Indemnification In Case Of Strict Liability Or Indemnitee Negligence. After the Closing, except in the case of fraud by the breaching Party, Sections 6.1 and 6.2 shall provide the exclusive remedy for any misrepresentation, breach of warranty, covenant, agreement or other obligation.

SCHEDULE 8.12 DISPUTE RESOLUTION PROCEDURES 1. Resolution of Disputes. After the Closing, and in any specific circumstances prior to the Closing as expressly set forth in the Agreement, the Parties shall resolve any controversy or claim, whether based in contract, tort or otherwise, arising out of, relating to or in connection with the Agreement, the scope, breach, or validity of such Agreement; or the commercial or economic relationship of the Parties hereto ("Dispute") in accordance with this Schedule. The Parties' agreement to resolve Disputes pursuant to this Schedule survives the expiration or termination of the Agreement. 2. Negotiations between Senior Management. The Parties shall first seek to resolve any Disputes by negotiations between Senior Management (as hereinafter defined). 2.1 Prompt notification and referral to Senior Management. The Parties will promptly seek to resolve any Dispute by negotiations between Senior Management of the Parties who have authority to settle the controversy. When a Party believes there is a Dispute under the Agreement, that Party will give the other Party written notice of the Dispute (the "Notice"). Within ten (10) days after receipt of the Notice, the receiving Party shall submit to the other a written response. The Notice and response shall include (1) a statement of each Party's position and a summary of the evidence and arguments supporting its position, (2) the supporting documentation as to the circumstances leading to the Dispute, (3) the name and title of the senior executives who will represent that Party and who are duly authorized to settle the Dispute (the "Senior Management"), and (4) a schedule of the availability of the Party's Senior Management who will negotiate the dispute during the thirty (30) day period following the delivery of the Notice. 2.2 Meetings among Senior Management. The Senior Management shall meet at a mutually acceptable time and place within thirty (30) days after the date of the Notice and thereafter as often as they reasonably deem necessary to exchange relevant information and to attempt to resolve the Dispute. If a Senior Management intends to be accompanied at a meeting by an attorney, the other negotiator shall be given at least three (3) Business Days' notice of such intention and may also be accompanied by an attorney. All negotiations pursuant to this Schedule are confidential and shall be treated as compromise and settlement negotiations for the purposes of the Federal Rules of Evidence and state rules of evidence. 3. Mediation. If the Dispute has not been resolved within sixty (60) days after the date of the Notice given pursuant to Paragraph 2 of this Schedule, or if the Party receiving such Notice will not meet within the time periods set forth in that Paragraph, either Party may initiate mediation of the Dispute by sending the other Party a written request that the Dispute be mediated. The Party receiving such a written request will promptly respond to the requesting Party so that all Parties can jointly select a neutral and impartial mediator ("Mediator") and schedule the mediation session. 3.1 Mediation guidelines. The mediation contemplated by the Parties is intended to be a voluntary process in which a neutral third party, who has no power to decide the outcome, facilitates communication among the Parties to promote understanding among them and, where possible, to arrive at a mutually acceptable resolution of their Dispute. The Mediator will not have the authority to impose a settlement on any Party. 3.2 The mediation process. No formal rules of evidence apply to the mediation, and there will be no stenographic record of any mediation meeting. Itis expected that, in the mediation, each Party will have a representative who is not acting as legal counsel and who is authorized to make the decisions which are part of the mediation process. Although legal and other consultants may participate in the mediation sessions, the communications in the mediation are intended to principally be among Party representatives and the mediator. 3.3 Withdrawal from the mediation. A Party may not withdraw from the mediation until: (a) A settlement has been reached; (b) Both Parties agree that an impasse has occurred; or, (c) The Parties have participated in a mediation of a duration of at least three (3) days. 3.4 Confidentiality. The mediation process is confidential, and the Parties and the mediator will not disclose confidential information regarding the process to third parties. The information that is confidential includes, but is not limited to, all statements or communications made in the course of and relating to the subject matter of the mediation and which is made to or in the presence of any Party representative or participant, Mediator or other person. All such confidential information will be treated as compromise and settlement negotiations for the purposes of the Federal Rules of Evidence and state rules of evidence. The mediation sessions are private. Only the Parties, their representatives, and the mediator may attend the mediation sessions. Other persons may attend only with the permission of the Parties and with the consent of the Mediator. The Parties and the Mediator shall not disclose information regarding the proceedings, including settlement terms, to third parties, unless the Parties otherwise agree. All third parties shall agree in writing to keep such information confidential. All records, reports, or other documents received by the Mediator while serving in that capacity shall be confidential. The Mediator shall not be compelled to divulge such records or to testify in regard to the mediation in any adversary proceeding or judicial forum, unless the Parties otherwise agree. The Parties shall not rely on, or introduce as evidence in any arbitration, judicial, or other proceeding: (a) Views expressed or suggestions made by another Party with respect to a possible settlement of the Dispute; or (b) Admissions made by another Party in the course of the mediation proceedings; or (c) Proposals made or views expressed by the Mediator; or (d) The fact that another Party has or has not indicated willingness to accept a proposal for settlement made by the mediator, or other Party. Information or confidential information that is otherwise admissible shall not be rendered inadmissible in a subsequent proceeding solely because it was used in negotiations or a mediation pursuant to this Schedule. 3.5 Exchange of Information. If any Party has a substantial need for documents or other material in the possession of another Party, the Parties shall attempt to agree on the exchange of requested documents or other material. If they fail to agree, either Party may request a joint meeting with the Mediator who shall assist the Parties in reaching an agreement. At the conclusion of the mediation process, upon the request of a Party which provided documents or other material to the other Party, the recipient shall return the same to the originating Party without retaining copies thereof. 3.6 Expenses. All expenses of the mediation, mediator compensation, and the expenses of any witness and the cost of any proofs or expert advice produced at the direct request of the mediator, shall be borne equally by the Parties. The expenses of witnesses for a Party shall be paid by the Party producing such witness. 4. Arbitration. If the Parties are unable to resolve the Dispute pursuant to the negotiation and mediation provisions of this Schedule within thirty (30) days following commencement of the mediation proceeding, the Dispute shall be submitted to arbitration in accordance with the procedures set forth below. 4.1 Initiation of Arbitration. The arbitration shall be initiated by either Party delivering to the other a Notice of Intention to Arbitrate as provided for in Section 6 of the AAA Commercial Arbitration Rules. 4.2 AAA Guidelines. The arbitration shall be conducted by the American Arbitration Association in accordance with the Commercial Arbitration Rules and the Supplementary Procedures for Large, Complex Disputes (collectively, the "AAA Guidelines"). In the event of a conflict between the AAA Guidelines and this Schedule, this Schedule shall govern. 4.3 Location of arbitration.If any Dispute is submitted to arbitration, the arbitration shall take place in Houston, Texas. 4.4 Arbitration Tribunal. Unless the Parties agree to a single arbitrator, the arbitration shall be conducted before three (3) independent and impartial arbitrators, none of whom shall be appointed by either Party. Rather, the arbitrators will be selected in accordance with the AAA Guidelines, and shall be attorneys at law who have practiced commercial law for at least fifteen (15) years. All arbitrators, prior to their service, shall disclose all actual or perceived conflicts of interest involving the Dispute or the Parties. No arbitrator may serve if such arbitrator has a conflict of interest involving the subject matter of the Dispute or with the Parties. In the event the Parties agree to a single arbitrator, the selection of the arbitrator shall be made by mutual consent. The three (3) arbitrators (or the single arbitrator the Parties so chose) selected shall constitute the "Tribunal." 4.5 Procedures and governing law. The arbitration shall be governed by the United States Arbitration Act, 9 U.S.C. 1-16, to the exclusion of any provision of State law inconsistent therewith and which would produce a different result, and judgment upon the award rendered by the arbitrator(s) may be entered by any court having jurisdiction thereof. The Tribunal shall determine the claims of the Parties and render their final award in accordance with the substantive law of the State of New York exclusive of its conflict of law rules.The limitations on any actions will be determined under New York law. 4.6 Provisional remedies. The Tribunal may, in the course of proceedings, order any provisional remedy or conservatory measure, including but not limited to attachment, preliminary injunction or the deposit of specified security, which they consider to be necessary, just and equitable.The failure of a Party to comply with such an interim order, after due notice and opportunity to cure such noncompliance, may be treated by the Tribunal as a default and all or some of the claims or defenses of the defaulting Party may be stricken and partial or final award entered against such Party, or the Tribunal may award such lesser sanctions as they deem appropriate. A request for interim or provisional relief to a court shall not be deemed incompatible with the agreement to arbitrate or as a waiver of that agreement. 4.7 Preliminary Hearing. Within thirty (30) days after the Tribunal has been appointed, a preliminary hearing among the Tribunal and counsel for the Parties shall be held for the purpose of developing a plan for the management of the arbitration, which shall then be memorialized in an appropriate order. The matters which may be addressed include, in addition to those set forth in the AAA Guidelines, the following: (a) Definition of issues; (b) Scope, timing and types of discovery, if any; (c) Schedule and place(s) of hearings; (d) Setting of other timetables; (e) Submission of motions and briefs; (f) Whether and to what extent expert testimony will be required, whether the Tribunal should engage one or more neutral experts, and whether, if this is done, engagement of experts by the Parties can be obviated or minimized; (g) Whether and to what extent the direct testimony of witnesses will be received by affidavit or written witness statement; and (h) Any other matters which may promote the efficient, expeditious, and cost-effective conducting of the proceeding. 4.8 Management of the Arbitration. The Tribunal shall actively manage the proceedings as it deems best so as to make the same expeditious, economical, and less burdensome and adversarial than litigation. 4.9 Discovery. The Tribunal shall permit and facilitate such discovery as it shall determine is appropriate in the circumstances, taking into account the needs of the Parties and the desirability of making discovery expeditious and cost-effective. Such discovery may include pre-hearing depositions, particularly depositions of witnesses who will not appear personally before the Tribunal to testify, if there is a substantial, demonstrated need therefor. 4.10 Service of Papers and Documents. Papers, documents, and written communications shall be served by the Parties directly upon each other and the Tribunal. 4.11 Confidentiality. All papers, documents, briefs, written communication, testimony and transcripts as well as any and all Tribunal decisions shall be confidential and not disclosed to anyone other than the Tribunal, the Parties, or the Parties' attorneys and expert witnesses (where applicable to their testimony), except that upon prior written consent of both Parties, such information may be divulged to additional third parties. All third parties shall agree in writing to keep such information confidential. 4.12 Hearings. The Tribunal may limit the issues so as to focus on the core of the Dispute, limit the time allotted to each Party for presentation of its case, and exclude testimony and other evidence that it deems irrelevant, cumulative or inadmissible. Notwithstanding the Parties' agreement regarding arbitration venue in Paragraph 4.3 of this Schedule, upon motion of a Party, the Tribunal may temporarily relocate a hearing to a place designated by the Tribunal as may be necessary to hear the testimony of particular witnesses not subject to subpoena at the usual hearing site. The purpose of such temporary relocation is to permit a hearing at a place where such witnesses can be compelled to attend. With the consent of all Parties, the testimony may be recorded before a single member of the Tribunal. 4.13 Stenographic Record. There shall be a stenographic transcript of the proceedings, the cost of which shall be borne equally by the Parties pending the final award of the Tribunal. 4.14 Damages. The Tribunal is empowered to award only compensatory damages as they may be limited by the terms of the Agreement. Each Party hereby irrevocably waives any damages in excess of compensatory damages, including a waiver of any punitive or multiple damages. The Tribunal may, in their discretion, grant pre-award interest and, if so, such interest may be at commercial rates during the relevant period. The Tribunal may award all or a part of a Party's reasonable attorneys' fees and costs of arbitration, taking into account the final result of arbitration, the conduct of the Parties and their counsel in the course of the arbitration, and other relevant factors. The Tribunal shall, in a final award, assess the amount of the costs of the proceedings. 4.15 Draft of proposed award and final award. Prior to rendering their final award, the Tribunal shall submit to the Parties an unsigned draft of the proposed award and each Party, within five (5) Business Days after receipt of such draft award, may serve on every other Party and file with the Tribunal a written statement outlining any alleged errors of fact, law, computation, or otherwise ("Written Statement"). Within five (5) Business Days after receipt of the Written Statement of each Party, the Tribunal shall render their final award. Any arbitration decision or award shall conform as closely as possible to the order or judgment which would be rendered by a court of the State of Texas. Any arbitration decision or award shall state the reasoning on which it rests, including both findings of fact and conclusions of law although such reasons shall not be used as a basis for appeal or other judicial proceeding. 4.16 Consolidation of proceedings. If an arbitration proceeding is initiated by a Party under the Agreement, and if a Tribunal or Tribunals have been previously selected in arbitration proceeding(s) under the Agreement which have not yet begun ("Existing Tribunal(s)") the Parties shall determine whether the most junior arbitration will be consolidated for hearing with any Existing Tribunal. In ruling on such motion, the first Existing Tribunal should order consolidation if there are one or more common questions of law and fact, and the interests of justice, expedition and economy would be served by consolidation. 4.17 Res Judicata. To the extent permitted by the law, any award by the Tribunal shall not be res judicata or have any binding effect in any unrelated litigation or arbitration where any Party to the Agreement may also be a Party. 5. Deadlines. All deadlines specified in this Schedule may be extended by mutual written agreement. 6. Performance. Each Party is required to continue to perform its obligations under the Agreement pending final resolution of any Dispute. 7. Injunctive Relief. The procedures specified in this Schedule shall be sole and exclusive procedures for the resolution of Disputes between the Parties arising out of or relating to the Agreement. However, if equitable remedies are not available to a Party because the Tribunal may not be timely convened as required for the relief sought, a Party may seek a preliminary injunction or other preliminary judicial relief, if in the judgment of that Party, such action is necessary to avoid irreparable damage or to preserve status quo. Despite the initiation of any such judicial proceedings, the Parties will continue to participate in good faith in the procedures specified in this Schedule. As between all Parties, all applicable statutes of limitation shall be tolled while the procedures specified in this Schedule are pending; the Parties will take all actions, if any, required to effectuate such tolling.
